Beginning April 13, 2016 I have been unable to delete the 2700+ emails in my deleted email section of windows live 2012. When I attempt to do so I receive a message that an unknown error has occurred. 

After speaking with both Dell tech support and my ISP's support individuals, I was asked to log in to my Outlook account. I did so and there is absolutely no mail there.

I was referred to the following:  http://answers.microsoft.com/en-us/windowslive/forum/livemail-sync/unable-to-delete-emails-for-my-outlookcom-account/4d4d85af-c04b-43e5-81d5-3ea41ff53b29   I did read this forum and did as instructed without success in rectifying my issue.

I have not touched any of the properties associated with my windows live mail account as the Dell tech support individual did remotely review and found no issues. I have cleared all mail and trash from my ISP's email area.

There was an update that was installed on 4/13/16 and several others after the last one being 5/26/16. All are indicated as having been successful. For some unknown reason my computer began downloading Windows 10 on 5/17/16 however I was able to revert back to Windows 7 with assistance.

With all of that being said, is there a solution to my issue with my inability to delete the deleted items?
